UNITED STATES JOSEPHV L. KILLION, OF MINNEAPOLIS, MINNESOTA,

STORM-SASH OPERATOR AND LATCH.

Application filed February 17, 1923. Serial No. 619,783.

To @ZZ wlw/nt t may concern:

Be it known that I, Josnrrr L. KILLION, a citizen of the United States, residing at Minneapolis, in th-e county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Storni Sash Operators and Latches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and highly etlicient storm sash operator and latch, and to this end, it consists of the novel devices and combinations of devices hereinafter describe-d and defined in the claim.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a view partly in horizontal section and partly in plan showing the invention applied to a window frame and swinging storm sash mounted therein;

Fig. 2 is a perspective View of the invention removed from the window frame and sash;

Fig. 3 is a view principally in vertical section taken on the line 3 3 of Fig. 1, on an enlarged scale; and

Fig. 4 is a detail View with some parts sectioned on the line 4 4 of Fig. 3.

The numeral 5 indicates a window frame as an entirety, with the .exception of the sill 6 and outsid-e stops 7 against which a storm sash 8 is arranged to close, and which sash is held suspended for swinging movement from the window frame by separable fasteners, not shown.

The invention includes a pair of toggle levers 9 arranged to form a parallelogram and having one of the-ir ends pivoted at 10 to a bracket 11 rigidly secured by screws 12 to the inner face of the lower rail of the storm sash 8 at the horizontal center thereof. Formed with the bracket 11 is a linger piece 13 by which the storm sash 8 may be swung to and from a closed position. The other ends of the toggle levers 9 are expanded to form eyes 14 to receive a screw 15 having screw-threaded engagement with an anchor 16 provided with a base 17 which rests on the window sill 6 and is secured thereto by screws 18. The base 17 has the same pitch as the window sill 6 so as to rest direct-ly thereon and support the anchor 16 in an upright position. A drain 19 is formed in the base 17 and extends to the screw-threaded bore thereof to permit the escape of water and dirt. Formed with the upper end of the screw 15 is a thumb piece 2O having a binding shoulder or surface 21. A horizontal swinging latch 22 is attached to the pivot 10, between the toggle levers 9 and the bracket 11, and has at its free end a hook 23 arranged to interlock with the screw 15 to lock the storm sash 8 closed, as best shown inFigs. 3 and 4. A spacing washer 24 is interposed between the eyes 14 of the toggle levers 9. Obviously, by operating the thumb piece 20 to turn the screw 15 into the anchor 16 the eyes 14, latch 22 and washer 24 may be frictionally clamped between the anchor 16 and shoulder 21 to lock the toggle levers 9 and latch 22 against pivotal movement and thereby hold the storm sash 8 closed.

To open the storm sash 8 it is only necessary to operate the thumb piece 20 and there by turn the screw 15 suiiiciently out of the anchor 16 to release the pressure on the parts held between the anchor 16 and shoulder 21, swing the latch 22 out of engagement with the screw 15, and move said sash outward by taking hold of the linger piece 13. IVhen the storm sash is at the desired position, the thumb piece 20 may be operated to again turn the screw 15 into the anchor 16 and thereby frictionally clamp the eyes 14 of the toggle levers 9 and the washer between said anchor and shoulder 21. Then the toggle levers 9 are thus held against pivotal movement, the storm sash will be securely held open and prevented from rattling and at the same time prevent the wind from lifting the storm sash and thereby release the separable fasteners holding the storm sash. By the use of the above described invention the storm sash may be held open in any desired position.

In removing the storm sash from the window frame it is only necessary to remove the screw 15 from the anchor 16 and detach the eyes 14 therefrom to release the toggle levers 9. The toggle levers 9 and latch 22 are permanently pivotally attached to the bracket 11 and hence cannot be detached therefrom or lost. The screw 15 may again be place-d in the anchor 16 or tied or otherwise secured to one rof- ,the parts of the sash-operator or latch.

The above described invention 1121s,' in actual usage, proven.vhighlyfctfcient for-the purpose had in View.

What I claim is:

A storm sash operatorandlatch compris-W toggle levers andthe hookfactingflatchwbe ing pvoted to the bracket and the other linksvof the toggle leversqbeingpivoted to said screw, said hook-acting latch being arranged to be nterlocked with t-he screw by a Asiviri-ging'movement Itransversely of the movement of the toggle levers, sai-d thumb screw Yaffording common means for simultw neouslvclamping the respective links of the toggle levers andthe hook-acting` latch the one upon the other..andontothe anchor `to rictionallyvholdthe toggle levers and hookacting datch againsbpivotal movement.
